Abstract
A three-phase separator taking nitrogen as a dynamic gas source is applied to three-phase separation of produced liquid of oil producing wells. A separated gas outlet is connected with a gas injection pipeline which is provided with a valve, the other end of the gas injection pipeline is communicated with a nitrogen bag, a communication pipeline is connected on the gas injection pipeline between the valve and the three-phase separator, the other end of the communication pipeline is connected onto an oil exhausting pipeline, a valve is connected onto the communication pipeline, a depressurizing emptying pipeline is connected onto the gas injection pipeline between the valve to the three-phase separator, and a valve is connected onto the depressurizing emptying pipeline. The three-phase separator taking nitrogen as the dynamic gas source has the advantages that the nitrogen is utilized as the external dynamic gas source, so that the three-phase separator can be used in small block-faulted oilfields without associated gases for oil-water separation of producing liquid.
Description
Technical field
The utility model relates to the oil extraction in oil field technical field, particularly a kind of three phase separator of oil well produced liquid, be a kind of without the associated gas oil field use with the three phase separator of nitrogen as power gas source.
Background technology
Oil field development is to the intermediary and later stages, and oil well produced liquid is moisture progressively to rise, and general Produced Liquid is moisture between 30～90%.Produced Liquid need to be processed into moisturely less than 5% crude oil, just can transport to the refinery.Oil well produced liquid quite a few is arranged in moisture is that state with free water occurs, purify (dehydration) before at crude oil depth, need be deviate from this part free water.Usually adopt three phase separator, when removing natural gas, tell free water.
At present, the structure of existing three phase separator is very ripe, and its project organization and manufacturing process respectively have advantage.The principle that the horizontal three-phase separator application of weight is separated is separated oil gas water three phase.Inner chamber top at horizontal three-phase separate eliminator is air chamber, and isolated natural gas is flowed through in horizontal direction and pounced on day with fog and flow out, and makes horizontal three-phase separate eliminator maintain certain pressure by pressure-control valve; Weir plate is again with lower part shared oil chamber and the hydroecium of container.The fluid that enters horizontal three-phase separate eliminator at first reaches hydroecium top, and under Action of Gravity Field, water is separated to the bottom, and face waterborne is crude oil, and the top of crude oil is natural gas.Here it is three phase separator is with the principle of oil well produced liquid three phase separation.
But because the part oil field does not have associated gas, can not in oil well produced liquid, isolate natural gas, can't use three phase separator that oil well produced liquid is separated.Therefore, oil field associating petroleum transferring station exist operating load large, draw oil costly, to the problems such as consumption height of conventional energy resource.
The utility model content
The purpose of this utility model is: a kind of three phase separator take nitrogen as power gas source is provided, can be used for the water-oil separating without the little fault block oil well produced liquid of association source of the gas.These oil fields are not being had in the situation of associated gas, oil well produced liquid is carried out the pre-separation of oil gas water, reduce oil field associating petroleum transferring station and keep normal production to the consumption of conventional energy resource.
The technical solution adopted in the utility model is: the three phase separator take nitrogen as power gas source, comprise three phase separator, valve and nitrogen bag, and inlet is arranged at the top of three phase separator one end, and oil well produced liquid enters in the three phase separator by inlet.The other end of three phase separator has delivery pipeline and flowing line, and isolated oil and water can be discharged.Blowdown pipeline is arranged at the bottom at three phase separator, and the foreign material of precipitation can be discharged by blowdown pipeline.The divided gas flow outlet is arranged at the top of three phase separator, it is characterized in that: the divided gas flow outlet of three phase separator connects the tonifying Qi pipeline, and the other end of tonifying Qi pipeline is communicated with at the nitrogen bag, at the tonifying Qi pipeline valve is arranged.Make three phase separator keep certain operating pressure by replenishing nitrogen.Be connected with connecting pipeline at valve to the tonifying Qi pipeline between the three phase separator, the other end of connecting pipeline is connected on the delivery pipeline, is connected with valve at connecting pipeline; Be connected with the pressure release blow-down pipe at valve to the tonifying Qi pipeline between the three phase separator, be connected with valve on the pressure release blow-down pipe.When the operating pressure of three phase separator is too high, can directly enter atmosphere by the pressure release blow-down pipe.
The beneficial effects of the utility model: the three phase separator of the utility model take nitrogen as power gas source, utilize nitrogen to make the external connection power source of the gas, can use three phase separator that Produced Liquid is carried out water-oil separating at the minor block oilfield without associated gas.Solved the difficult problem that to carry out the profit pre-separation without the oil field of associated gas to oil well produced liquid.Adopt three phase separator that Produced Liquid is carried out the profit pre-separation, can reduce crude oil heating and learn dehydration and the front heat requirement of crude oil electric dewatering, reduced oil field associating petroleum transferring station and kept normal production to consumption and the crude oil roping expense of conventional energy resource.
